Would like to have the ability to actually hide rows that are selected to be hidden. Makes review of specific rows quick. Otherwise will just keep using Excel.
Can you clarify a bit? Do you mean you'd like to hide rows in the data table display? As opposed to the current features to keep rows from appearing in graphs and plots.
I completely understand the need for focusing attention on particular rows. In JMP, my favorite way to do this is the Data View, which you can invoke by selecting whichever rows you wish to focus on, then right-click the Selected line in the Rows section of the data table, then select Data View. The new table view you get is a linked subset of the table, allowing you to make edits, create selections, or simply view just that subset of the data (see gif below). Once you're done viewing that subset you simply close the table.
I have found this to be a much more effective way to focus attention than hiding rows, which I used to do in Excel as well. Hope this is helpful.
To answer your question, yes I would like to hide rows from being displayed in a data table view to focus on those that are selected. Skips have to select and using F7 to find highlighted rows or creating a new table of just those selected but creating a distribution of a categorical column and double clicking on the bar of the data of interest. Want this ablilty on one or more columns at the same time too plus being able to select more than one group within a column. Thinking of big class file it would be like filtering out all but one sex and then by one or more age. I deal with files with rows in the 000's and 000,000's so quick selection by using the new dist feature in JMP15 would be awesome. Just trying to get out of using Excel. As for data filtering a table Excel is superior (and that's about the only thing).
